Hex Dec Type/Val Lng Label (dup) Comments ---- ---- --------- ---- -------------- -------- 0000 0 Structure LRBK Map the Load Request Block 0000 0 Address 4 LRBPPFWD Address of next LRBK on the system initialization chain of post-initialization processing control blocks. 0004 4 Signed 4 LRBPPPRI Priority value for ordering entries on the chain. Higher values come later on the chain. Equal values are ordered LIFO or FIFO as needed by the use of the control block. 000002FD LRBPRTY 765 Priority value for LRBPPPRI. Arbitrary, but unique for LRBK control blocks on the SYSPPROC chain. 0008 8 Dbl-Word 8 LRBUSRD1 Reserved for non-IBM use 0010 16 Dbl-Word 8 LRBUSRD2 Reserved for non-IBM use 0018 24 Signed 4 LRBUSRF1 Reserved for non-IBM use 001C 28 Signed 4 LRBUSRF2 Reserved for non-IBM use 0020 32 Signed 2 LRBUSRH1 Reserved for non-IBM use 0022 34 Signed 2 LRBUSRH2 Reserved for non-IBM use 0024 36 Bitstring 1 LRBUSRX1 Reserved for non-IBM use 0025 37 Bitstring 1 LRBUSRX2 Reserved for non-IBM use 0026 38 Bitstring 1 LRBUSRX3 Reserved for non-IBM use 0027 39 Bitstring 1 LRBUSRX4 Reserved for non-IBM use 0028 40 Character 32 LRBFID (0) File being loaded 0028 40 Character 8 LRBFIDFN File name 0030 48 Character 8 LRBFIDFT File type 0038 56 Signed 2 LRBFIDFM File mode 003A 58 Signed 2 * Reserved for future IBM use 003C 60 Address 4 * Reserved for future IBM use 0040 64 Character 8 LRBFIDMB Member name 0048 72 Character 8 LRBID ID string for the CPXLOAD operation. This ID string is used in the CPXUNLOAD command to identify this CPXLOAD request. The format of LABID is explained in the descriptions of LABIDH and LABIDL. 0050 80 Character 8 LRBCTLEP The control epname to call during CPXLOAD processing and before CPXUNLOAD processing. 0058 88 Signed 4 * Reserved 005C 92 Signed 4 LRBRC Final return code 0060 96 Address 4 LRBGSDQ Address of 1st GSDBK in chain . of error message GSDBKs 0064 100 Address 4 LRBGSDQE Address of end GSDBK in chain . of error message GSDBKs 0068 104 Address 4 LRBESDQ1 Address of chain of ESD entries built during processing of the present portion of TEXT stmts. 006C 108 Address 4 LRBESDQ2 Address of chain of ESD entries built during processing of the prior portions of TEXT stmts. Bit definitions in LABK.LABBF should match the bit definitions in LRBK.LRBBF.

If the ID was assigned by the user, then this low order word of the ID field LRBID will be the second 4 characters of the ID.
